The taxonomy of the tufted capuchin is debated. Some researchers list certain types as subspecies while others elevate the same types to full species level (see Rylands et al. 2005). Groves lists six subspecies: C. a. apella, C. a. fatuellus, C. a. margaritae, C. a. macrocephalus, C. a. peruanus and C. a. tocantinus. He lists C. libidinosus, C. nigritus, and C. xanthosternos as discrete species, although some researchers place these as subspecies of C. apella (Groves 2001).

Cebus apella
RANGE
CURRENT RANGE MAPS (IUCN REDLIST): Cebus apella The tufted capuchin is only found in South America, in the countries of Colombia, Ecuador, Peru, Bolivia, Brazil, French Guiana, Suriname, Guiana, and Venezuela (Fragaszy et al. 2004). The Margarita island tufted capuchin (C. a. margaritae) is isolated from the rest of the population off of the north coast of Venezuela and is separated from the nearest mainland population by around 800 km (Groves 2001; reviewed in Fragaszy et al. 2004). This population presumably has been on the island since the pre-Columbian era but, ultimately, its origin is unknown (Groves 2001). The heart of the range of the tufted capuchin is the northwestern half of Brazil and the Amazon basin. It is found in western Amazonia, and in the middle and lower Rio Amazonas and the Guianas. Its northern limit extends up to Venezuela as far as the Federal Territory of Amazonas and is limited by savannahs. The west of the tufted capuchin range extends into the Columbian Amazon and as far as the eastern foothills of the Andes mountain chain south into Peru. The southern limit in Brazil appears to be limited by the bush savannah of central Brazil. Eastern extremes of the range may extend past the Rio Xingu but there is some dispute as to the limits of the range (Rylands et al. 2005). The tufted capuchin has the largest range of all of the New World primates (Freese & Oppenheimer 1981). Tufted capuchins were studied for over ten years at La Macarena, Colombia by Kosei Izawa starting in 1986 (Izawa 1988). Other prominent studies include those in Peru by Charles Janson.HABITAT
The genus Cebus as a whole inhabits almost every type of forest in the neotropics. The same can be said about the tufted capuchin which can live in many different habitats as well (Mittermeier & van Roosmalen 1981). It can live within a wide variety of wooded habitats and is regarded as being considerably adaptable. In Suriname, it lives in at least five different forest types, including high rain forest, low rain forest, mountain savanna forest, liane forest, and pina swamp forest (Mittermeier & van Roosmalen 1981; see Zhang 1995a). In general, habitats in which tufted capuchins are found include rain forest, southern forest, mora forest, premontane forest, lower montane forest, wallaba forest, kanuku forest, southeast seasonal forest, swamp forest, and low seasonal forest (Lehman 2004). They are also found in a range of different edge habitats. Within different forest types, the monkeys typically remain within the understory and lower and middle canopy (Mittermeier & van Roosmalen 1981). Near the eastern end of the tufted capuchin range in French Guiana, the climate has an annual dry season from August to November and a long rainy season punctuated in February and March by a short dry spell. Annual precipitation averages 3000 mm (118.11 in) and temperatures range from 22.0°C (71.6°F) to 31.2°C (88.16°F) (Zhang 1995a). In the middle of the tufted capuchin range, near Manaus, Brazil in dense terra firma forest, mean average rainfall is 2,673 mm (105.24 in). This area exhibits a wet season from December to May and a dry season during the rest of the year. Temperatures can range from 21°C (69.8°F) to 33.5°C (92.3°F) at this locale (Spironello 2001). Near the western extreme of the tufted capuchin range in moist tropical forest in southeastern Peru, the dry season ranges from June to October and rainfall averages around 2000 mm (78.74 in) with an average temperature of 24.1°C (75.38°F) (Janson 1985). The altitude at which tufted capuchins are found also can vary considerably with the species having been seen as high as 2350 m (7709.97 ft) in the Peruvian highlands (Butchart et al. 1995).ECOLOGY
The omnivorous tufted capuchin is able to exploit a wide range of food resources, including many not used by other neotropical primates, a fact that permits its widespread distribution (Brown & Zunino 1990). As would be expected in such a large range, foods exploited by tufted capuchins vary widely with habitat as well as with the seasons. In general, the tufted capuchin diet contains fruits, insects, leaves, nectar, nuts, and pith, the relative proportions of which in the diet vary considerably with the seasons (Terborgh 1983; Spironello 2001). In Suriname, the tufted capuchin eats mainly insects and fruits supplemented by seeds, flowers, and leaves (Mittermeier & van Roosmalen 1981). Elsewhere in Amazonia, the diet of the tufted capuchin was 82% plants and 18% animal matter. A larger number of different species of plant are used during the wet season than are used in the dry season (Spironello 2001). In the dry season, when food is often scarce, the tufted capuchin relies on palm nuts and pith for nourishment as this resource is readily available in an otherwise lean resource season. In the wet season however, the reliance on palm is curtailed as other food resources are available (Terborgh 1983). Animal prey of the tufted capuchin includes a large variety of insects in addition to vertebrates such as frogs, lizards and birds (Terborgh 1983). In addition to other vertebrates, the tufted capuchin is a confirmed predator of titi monkeys (Callicebus moloch) having been observed killing and consuming an infant (Sampaio & Ferrari 2005). The main activity of tufted capuchins over the course of the daily activity period is feeding (Izawa 1980). On a daily basis, the diurnal tufted capuchin will divide its time into 12% rest, 21% travel and 66% feeding (Terborgh 1983). Time spent in different daily activities varies with the seasons and locality and foraging time can range between January and May from 2% of daily activity to 37.1%. Movement can range from 35.2% to 23.6% of time spent daily (Zhang 1995a). Tufted capuchins rest more and travel less with a greater availability of fruits and other food resources in the wet season. Tufted capuchin foraging for insects increases in the dry season, presumably due to the lack of available fruit resources (Terborgh 1983).

SOCIAL ORGANIZATION AND BEHAVIOR
Tufted capuchin social organization is characterized by discrete hierarchies of rank between both sexes and different age classes (Izawa 1980). Both male and female rank hierarchies are correlated with age, with the older individuals typically being higher ranked than younger individuals (Izawa 1980). Tufted capuchin groups are often small, numbering in the teens or lower twenties with only one to several adult males and around the same number of adult females (Izawa 1980; Defler 1982). It is suggested that when troop size approaches around twenty individuals, the chances of group fission increase and such fission limits group size (Izawa 1994). There is some evidence that tufted capuchin society might be matrilineal, as matrilines remain together when group fission occurs (Izawa 1994). Tufted capuchin group home ranges can overlap, often with the ranges of more than two groups overlapping the same area (Spironello 2001). This common territory is the result of the lack of territorial defense by a single tufted capuchin group (Defler 1982). When different groups encounter one another, interactions range from peaceful curiosity and tolerance of the other group to active chasing away by adult males (Defler 1982; Spironello 2001).

REPRODUCTION
The tufted capuchin mating system is difficult to classify as it is multi-male/multi-female the majority of the time but can also be single-male. That is, often most males can potentially mate with most females, but under certain conditions only the alpha male will mate (Carosi et al. 2005). Perhaps the most characteristic aspect of the tufted capuchin mating system is the active female solicitation of the alpha male and female choice of mate. Males solicit mating far less often then do the female tufted capuchins and seem to respond to female solicitation rather than to initiate it (Welker et al. 1990). Female behavior is the only indication of estrus, as there are no external clues or genital swelling which might indicate an estrous state (Carosi et al. 2005). Estrus lasts from one to eight days but typically lasts around five days (Janson 1984; Phillips et al. 1994). In addition, estrus does not show any strict seasonality although it is more common in some times of the year than others and conceptions are somewhat synchronous among females (Janson 1984). Birth season varies by locale and reflects the differential rainfall, food availability and photoperiod of the habitat (Carosi et al. 2005). Female tufted capuchin behavior changes noticeably during estrus and they become skittish, with consistent grimacing and characteristic estrus vocalizations resembling a whistle or a whine. In addition, during the first several days of estrus, the alpha female will approach and follow the alpha male and constantly and actively solicit him. These solicitations are similar to overall estrus behavior and take the form of vocalizations, distinctive submissive postures, grimaces, and rapid touching and fleeing (Janson 1984). The alpha male’s response is initially indifferent and deterrent but after several days he becomes receptive and copulations, up to one per day, will occur (Janson 1984; Carosi et al. 2005). Sexual solicitation by females of alpha males is extremely adaptable, changing focus almost immediately when a formerly subordinate male attains alpha status (Carosi et al. 2005). In other words, when a male attains alpha status, females will immediately start soliciting him when they previously ignored him due to his subordinate status. Toward the end of estrus, females will stop soliciting and mating with the alpha male and will mate with several other lesser-ranked group males in a short period of time (Janson 1984). Copulations involving an alpha male will typically last much longer than those involving subordinate males (Janson 1984). There are conflicting reports regarding male-male or female-female aggression during tufted capuchin mating behavior. While some researchers have observed little aggression during matings, others have reported aggressive interference of copulations of lower ranking individuals by both males and females (Janson 1984; Phillips et al. 1994; Linn et al. 1995). These differences may reflect differences in the group size, age-sex composition and degree of relatedness among group members. Subordinate male sexual behavior may also be inhibited in the presence of dominant males, at least during the middle days of female estrus (Linn et al. 1995; Visalberghi & Moltedo 2001). This inhibition and active solicitation of males by females may account for the generally lower levels of aggression than is seen in other species with multimale/multifemale breedings systems (Carosi et al. 2005). Female solicitation postures can take several forms including the female facing the male, grimacing at him, and spreading her thighs or the second posture which has her facing away from the male and looking back over her shoulder at him. Following this posturing, copulation will occur and can last up to four minutes (Janson 1984). Post copulation, a sperm-plug is formed which may serve as a means for a male tufted capuchin to increase his chances of producing offspring (Carosi et al. 2005).

PARENTAL CARE
The average weight of a captive tufted capuchin at birth is 210 g (7.4 oz) (Fragaszy & Adams-Curtis 1998). At birth and for the subsequent three weeks in the wild, the infant will cling dorsally to its mother and not move independently (Calle 1990). In addition, for the first two weeks of life in the wild, the majority of the mother’s resting time is spent suckling and grooming the infant (Calle 1990). Transportation in the first month is provided by the mother, who also provides food for the infant for the first two months (Valenzuela 1994). After the fourth week of life, 20-70% of the infant’s time is spent with alloparents of all demographics which is an indicator of strong group cohesion (Valenzuela 1994). Carrying by other group members occurs predominantly while the mother feeds and while the group is moving (Escobar-Páramo 1989). By the third month, infants move independently except in situations in which the group must move very quickly (Valenzuela 1994). As wild infant capuchins gain independence and are capable of solitary movement, they typically gravitate toward and stay near the alpha male (Escobar-Páramo 1989). Their affiliative bond of the infant with the alpha male is stronger and more evident than with subordinate group males (Calle 1990). At around nine months, infant facial coloration lightens above the eyebrows. In addition, contrasts in pelage color become more profound between the shoulders and the rest of the body (Escobar-Páramo 1989). Because females produce offspring only about once every two years, it is assumed that complete weaning takes place into the second year as having a dependent infant precludes reproduction at the one year mark (Robinson & Janson 1989). Wild weaning has been estimated at around 16.5 months and captive weaning at 13.7 months (Fragaszy & Adams-Curtis 1997). While development in captivity is better recorded than in the wild, it is suggested that infant development in wild populations of tufted capuchins is faster than of those in captivity because of the difficulties of a wild existence versus a captive one (Valenzuela 1994). Up until the fifth week of life, sleep predominates in the daily activity of the captive infant tufted capuchin (Byrne & Suomi 1995). In captivity, infants begin to explore their surroundings between three and eight weeks of age (Byrne & Suomi 1995). In addition, an infant will constantly remain in contact with its mother until the second or third month of life (Byrne & Suomi 1998). From two to six months of age, the proportion of time spent alone grows as time spent with the mother decreases and by six to seven months more time is spent alone than with the mother (Byrne & Suomi 1995). Captive allomothering commences in the eighth week of life (Fragaszy et al. 1991). After the third month of life, adult males in captivity are also approached preferentially by infant capuchins with the male being approached more often than all the females combined save for the mother (Fragaszy et al. 1991). Social play is first seen after 14 weeks of life between the infant capuchin and other infants, juveniles and adults, particularly the adult males (Fragaszy et al. 1991). By one year of age, fine motor control is almost completely developed at the adult level and by 15 months of age, truly independent foraging is seen (Fragaszy & Adams-Curtis 1997).COMMUNICATION
Vocal communication in the captive tufted capuchin consists of several calls which serve specific purposes. Contact calls are either the “mik” or “ik” vocalizations and to reestablish contact with the group when separated, a “fueh” call is given. Warning and alarm vocalizations include “e-c-k-g,” “i-tsch-g-k,” and “ik-a” sounds. Upon utterance of alarm vocalizations, the entire troop will flee. The four to five second “p-ru-pju-uiu-uiu-uiu-u” call is possibly given to signal intent to establish a new group as only females responded to this call uttered by a male who was separated from the group (Dobroruka 1972).LISTEN TO VOCALIZATIONS

CONSERVATION THREATS
Threat: Harvesting (hunting/gathering)
Hunting for food and as a crop pest of the tufted capuchin is also a significant threat to its numbers. Fragmentation of tufted capuchin habitat also serves to bring the species into further contact with people causing crop-raiding conflict as well as facilitating hunting access (Fragaszy et al. 2004). In one instance, a village of indigenous Brazilians killed and consumed over two hundred tufted capuchins in under a year (Nascimento & Peres cited in Chapman & Peres 2001).LINKS TO MORE ABOUT CONSERVATION
